Inverter for grid connection energy system

Has some thought already gone into how to connect an inverter for grid feedin/self use to the battery system? Any tips on how to implement this part?

@frankrichter and Thomas Plaz have built up a battery system that feeds into the grid using AE conversion inverters. They described the build-up of the battery in lots of detail here, but I’m not completely sure how the communication with the inverter works. Maybe @frankrichter has some links or further information how they implemented that.
